HOLDING-FLASK.

Specification of Letters Patent.

Patented Sept. 13, 1921.

Application filed July 9, 1920. Serial No. 394,981.

To all whom it may 0011mm:

Be it known that FRANK M. Bronnow, residing at Jeannette, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Molding-Flasks, of which the following is a specification.

The object of the invention is to rovide a method and ap aratus for forming the members of glass askets and similar articles having attached handles of the bale or loop form, the purpose being to provide for the molding of the handle in one piece and co-incidentally with the body of upper frame of the basket or like article, to avoid the necessity of separately molding and attaching the handle subsequently and as a separate operation from that involved in the construction of the body of the basket or equivalent receptacle; and with this object in view, the invention consists of the combination and construction of parts, of which a preferred embodiment is shown in the drawings, wherein Figure 1, is a side view of a flask molding invention.

Fig. 2, is a similar view taken in a line at right angles to that of Fig. 1.

Fig.3, is a to plan view.

Fig. 4, and ig. 5, are sectional views respectively of the plans indicated by the lines 44: and 55 of Fig. 3.

Fig. 6, is an inverted perspective view of the top element.

Fig. 7, is a perspective view of the intermediate element.

Fig. 8, is a similar view of the base memher.

The flask consists essentially of the base member 10 which is provided with a molding seat 11 having confi rations designed to produce a rece tacle 'p or rim of the desiredform or s ape, and super-posed upon this base member is a removable cap member 12 provided with a molding face 13 which is complemental to the seat in the base member to effect the holding of the opposite surface of the rim 14 of the basket or other receptacle which is to be produced thereby and the form of which obviously is variable to suit the design of the proposed molded article. This cap member is of sectional construction and comprises a top element 15 and an intermediate element 16 of which the latter is preferably rovided with suitable handle 17 which may readily manipulated, the cap member being provided with depending positioning lugs 18 for reception by sockets 19 in the base member to properly locate the members relative to each other in removing the members of the flask.

The division line between the top element and the intermediate element comprising the cap member is on an oblique plane as indicated at 20, and in the meeting faces of the top. and intermediate elements there is provided a molding channel 21 represented by registering grooves formed respectively in said surfaces and communicating with pockets 22 provided in the rim 11 of the base member, so that as the molden glass is molded in the flask by any well known or preferred methods, the material is forced into the registering grooves in the obliquely disposed meeting faces of the top and intermediate elements of the cap member to provide a loop of the material of the chosen cross sectional size and contour, which is integrally joined to the material forming the rim or lip of the molded vessel to the end that when the glass has become partly set, the top member is removed and, the portion forming the handle of the vessel which lies in the groove in the oblique face of the intermediate element is exposed at its other side. Having removed the top element the handle of the intermediate element may then be grasped by the operator and the intermediate element pivoted upon its free diameter which is fulcrumed to bend the loop of pliable glass before it has become hardened into an upright position or a position perpendicular to the plane of the molded flange or rim or lip of the receptacle, aft-er which the remainder of the elements may be removed as in the ordinary procedure.

Thus the handle of the receptacle may be molded as an integral part of the receptacle and be made attachable on the rim or flange thereof and put into the proper position with relation to the rim or flange while in such a condition as to be manipulated in this way, so that when the material hardens, the handle will constitute an integral part of the vessel and may be so an nealed to avoid a separate operation or the separate formation and attachment of the handle to the vessel.

The invention having been described,

bers of ahandle molding channel.

2. A flask for molding receptacles with attached handles having base and cap members provided with-"complemented rib form- 'ing "faces, disposed in spaced relation with eachotherfthe cap member comprising separable top and intermediate elements provided 1 in 1 their meeting 1 faces with 1 registering grooves forming complemental members ofa handle molding channel.

A flask for molding receptacles with attached ha'ndles' having base and cap members provided with 'complemental' rim molding "faces, %pockets being provided in the molding face of -the base member and the capmember comprising separable top and intermediate elements provided in their meeting'faccs with registering grooves forming complemental members of a handle molding channel arranged in terminal communication with said pockets in the base member.

4;. A flask for molding receptacles with attached handles having base and cap members provided with complelnental rim molding faces, the cap member consisting of separable top and intermediate elements meeting on an oblique plane and provlded in their meeting faces with registering grooves forming a channel in terminal communication with the spaces between the rim mold 'in'gfaces of the cap and base members.

In" testimony whereof he aflixes his signature.
